Abstract (en)
[origin: EP3565279A1] The present technology relates to an audio signal reproduction apparatus and a reproduction method, a sound pickup apparatus and a sound pickup method, and a program capable of matching listening timing from individual speakers at a listening position with a simpler configuration.There is provided an audio signal reproduction apparatus including: a reproduction unit that reproduces an audio signal supplied to a speaker installed to be directed to a listening position; and an adjustment unit that adjusts a delay amount of the audio signal supplied to a target speaker in accordance with an interval of a measurement sound obtained from a picked-up signal with another speaker. The picked-up signal is a measurement sound picked up by a sound pickup apparatus installed at the listening position and is a signal including the measurement sound corresponding to a measurement signal, and the measurement signal is a signal that causes a plurality of speakers installed to be directed to the listening position to output the measurement sound at a predetermined time interval. The present technology can be applied to an audio signal reproduction apparatus such as an AV amplifier device and a wireless speaker.
